How to change reminders?

Al
I'm trying to set up my reminders, and for example it's telling me today to make my annual appointment, but it's not due for 6m. I'd like to change the reminder but it only lets me change the time, not the date. Also the repeat setting doesn't work for me. Is this a known bug? Also- where do we get support for this app??? Is this really the only option?? I can't find a "help" or "contact us" link anywhere in the app or the website.
